MDI/MDI-X Selector Switch
An RJ-45 port on a 10 Mbps Ethernet network device can have one of two
possible wiring configurations: MDI or MDI-X. The RJ-45 port on a PC, router
or bridge is typically wired as MDI, while the twisted pair port on a switch or
hub is usually MDI-X.
To connect two 10 Mbps network devices together that have dissimilar port
wiring configurations, such as MDI to MDI-X, you use a straight-through
cable. To connect two network devices that have an RJ-45 port with the same
wiring configuration, such as MDI to MDI, you use a crossover cable.
The RJ-45 port on the media converter features an MDI/MDI-X switch. You
can use this switch to configure the twisted pair port on the media converter
as either MDI or MDI-X. This feature allows you to use a straight-through
cable regardless of the type of end-node connected to the port.
